What is @types/prop-types?
The @types/prop-types package is a TypeScript declaration package that provides type definitions for the prop-types library, which is used for runtime type checking of React props. It allows developers to use prop-types in TypeScript projects and get type checking and IntelliSense support in their code editors.
Type checking for React props
This feature allows developers to define type checking for the props of a React component. The code sample shows how to use PropTypes with TypeScript to ensure that the props passed to a component are of the correct type.
{"import PropTypes from 'prop-types';
interface MyComponentProps {
name: string;
age: number;
isStudent: boolean;
}
const MyComponent: React.FC<MyComponentProps> = ({ name, age, isStudent }) => (
<div>
<p>Name: {name}</p>
<p>Age: {age}</p>
<p>Is a student: {isStudent ? 'Yes' : 'No'}</p>
</div>
);
MyComponent.propTypes = {
name: PropTypes.string.isRequired,
age: PropTypes.number.isRequired,
isStudent: PropTypes.bool
};"}
